IBEVEL ATTACHMENT FOR BENCH-PLANES'.

Specification of Letters Patent No. 31,707, dated March 19, 1861.

To all whom 'Lt 'may concern:

Be it known that I, `LEONARD O. F ATR- BANKS, of the city of Nashua, county of Hillsboro, and State of New Hampshire,

have invented a neuT anduseful Square and Bevel Attachment for Planes or other BenchwTools; and I do declare the following is a fulland exact description thereof, reference being` had to the annexed drawings.

The object of my invention is to enable persons using the ordinary bench planes t0 produce a square or any required bevel With certainty and despatch, Without the eX- traneous aid of square and bevels.

The nature of my invention consists in attaching to bench planes a clamp with an adjustable guide, and is constructed as follows: I construct a clamp A, Figure 1, of

such size as will readily receive between its lugs B and binding screw C the different sizesof planes, in such a manner that Will secure the plane of the lugs in the square of the plane, as shown in perspective (Fig. 2). To the lugs'is connected a guide plate D Whose proportion is such as to secure the steadiness of a guide. At the foot of the upright A and at right angles with the face of the guide D is an adbjusting screw H Which is operated by a stationary nut F. Vhen the clamp is attached to the plane the guide plate is adjusted either at right angles with the plane stock, for the purpose'of obtaining a square edge, or set at any required angle, for a' bevel, by means of the adjusting nut F. Y

IVhat I claim as my invention and for which I desire to secure Letters Patent is- The. attaching of an adjustable guide to the stocks of bench planes, substantially in the manner and for the purpose set forth. LEONARD O. FAIRBANKS. Witnesses:
